SHEET 3 OF 3 INVENTOR. DANIELQ. 130.11: SAMUEL TAYLOR PERIVlUTl sou KESTIN BYf': 2 g g 2 TRANSFER SLEEVE BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates generally to means for transferring materials from a discharge source and simultaneously extending the quantity of the material stored prior to subsequent removal, and, more particularly, to a waste receptacle changing assembly system in which a plurality of waste receiving transfer sleeves may be aligned so that the waste storage capacity is rendered extendible.

2. Description of the Prior Art Waste compactors are known. One such compactor is described in U.S. Pat. No. 3,384,007. Generally what is done in this prlor art compactor is to place an empty receptacle, such as a bag or standard garbage can, over the discharge end of the compactor and, when the receptacle is filled with waste, an attendaut removes the receptacle and places a new one over the dhcharge spout. However, this necessitates an attendant being available In the vicinity of the waste compactor so that the receptacles may be changed when filled.

It would, therefore, be advantageous if a receptacle changing system could be devised, which could be left unattended for long periods of time before the receptacle changing step.

SUMMARY OF THE INVENTION It is, therefore, among one of the principal objectives of this invention to provide such a system wherein the waste coming from a waste compactor is extendibly received, so that frequent bag changing is rendered unnecessary.

In accordance with the invention, this is accomplished by providing a transfer sleeve adapted to receive a waste receptacle. The transfer sleeve further comprises an open ended hollow body provided at one of its open ends with carrying means. The bag is enveloped over the sleeve via its other open end so that when the sleeve is filled with waste, the simple act of pulling the sleeve from out of the enveloping receptacle will result in the waste remaining behind in the receptacle.

Alternatively, the transfer sleeve can be used for transferring and storing any other materials flowable therethrough.

Tracks may be provided for holding a plurality of the aforesaid transfer sleeves in position at the discharge end of a waste compactor. The configuration may be in any workable geometric shape, e.g. straight line, circular, semicircular, or rectangular. The tracks can also be uniplanar or multiplanar. The tracks are provided with means for locking the transfer sleeves in a nesting relation therealong. However, when a track assembly is not available, according to another embodiment of the invention, the transfer sleeves may be adapted to be self-locking in tandem.

DESCRIPTION OF THE SPECIFIC EMBODIMENTS Referring now to the figures in detail and referring for ease of descriptive flow first to FIGS. 10 to 13, there is shown therein a transfer sleeve, sometimes hereinafter referred to as sleeve, constructed according to the invention. Sleeve 10 comprises an open ended hollow preferably cylindrical body 12 provided preferably with a circular rim I4 at the one end 16 thereof, said rim being integral with the body. A pair of opposing carrying means 18 are mounted to the body and preferably at the rim. The carrying means each further comprise a generally "U-shaped body 20 suitably affixed to the rim, such as by welding or bolting, with the closed portion 22 of the "U extending above the rim of the sleeve and the two leg portions 24 of the U" extending below the rim alongside the body of the sleeve while the body, as shown, is preferably U-shaped, it is to be understood that any suitable configuration such as a single bar, a curved bar, a square shaped bar and the like can be used. Alternatively, no separate carrying means need be provided, but instead, the rim may be outwardly flared to thereby serve as the carrying and/or locking means. A suitable waste receptacle 26, such as a paper or plastic bag, or a metal can, etc. is fittable over the body of the transfer sleeve via its other open end 17 so that the body of the sleeve is in telescopic enveloped relation with the bag when the bag is placed thereover. Thus, when a sleeve with a bag associated in the manner just described is filled with waste, the act of removing the sleeve from the bag will leave the waste contents formerly in the sleeve remaining in the bag. The inside diameter of the sleeve is preferably somewhat larger than the inside diameter of the discharge spout of the compactor to accomplish a reduction in friction.

Referring now to the remainder of the figures, when the sleeve I0 is used in association with a waste compactor 30, which is only fragmentarily shown in FIG. I, in the manner in accordance with the invention, a support, advantageously in the form ofa track assembly 34, is provided for holding a plurality of the sleeves in an axially aligned position at the discharge end 32 of the waste compactor.

Track assembly 34 comprises a pair of parallel opposing preferably tubular members 36, they could also be solid, interconnected by cross members 38. The track assembly may be made up of sections of independent units or as one track as described. Preferably, the track assembly is made up in several sections so that it may be readily transportable and assemblable. This is accomplished by providing a boss 40 at the end of each track section, which is telescopically fittable into the tubular members of the succeeding track section. Less preferably, the tracks may be aligned in an abutting end to end relation without the aid of the bosses. At least a pair of opposing preferably rotatable wheels 42 are mounted to each tubular member 36 of the track. This is accomplished by welding or bolting the wheel housing 44 containing each wheel 42 to each tubular member 36, and also preferably the first track section is pivotally mounted as at 37 at the discharge end of the compactor. The purpose of the wheels will become readily apparent directly.

A terminal track section 50 is provided for each track as sembly, which in turn comprises a pair of parallel opposing tubular members 52 which are telescopically fittable into the tubular members 36 of the track assembly, or slidably arranged when the track members are not tubular. A vertically extending back plate 70 is provided at the end of the tubular members 52. A limiting switch 54 is provided in association with terminal section 50, which limiting switch acts by conventional means, well known in the art, to turn off the waste compactor when the terminal section 50 has reached its maximum xtension point. Of course, the limiting switch is wired to the erminal section 50 and to the compactor 30 by conventional neans, well known to the art, and need not be further lescribed, the invention lying elsewhere.

Each cross member 38 comprises a connecting rod 54 otatably mounted inside a pair of opposing collars 56, each ollar 56 being in turn mounted to each tubular track member '6. The collars 56 are mounted to the tubular members 36 by onventional means, such as welding. There is in turn mounted to connecting rod 54 and between tubular members 6, a curved angle bar 58, which is curved to associatingly, moothly receive a transfer sleeve to thereupon. Thus by virue of curved angle bar 58 being mounted to rotatable con- .ecting rod 54, it will follow that angle bar 58 is likewise otatable between the tubular members 36. The importance of his will be very shortly seen. A support member 57 is proided for each track member 36, in order to hold the track as' embly in spaced relationship with the ground.

Support for the sleeve may also be accomplished by provid ng interconnecting means associated with each sleeve thereby liminating the necessity of an additional independent support tructure e.g., track assembly, or otherwise. These intercon' lecting means comprise associated releasable locking means lrovided on the rim l4 and bottom 17 of the transfer sleeve. )n the rim there is provided a bayonet slot 100, and ireferably a pair of opposing bayonet slots, and on the bottom If the sleeve there is provided a bayonet-type projecting neans 102. Thus the sleeves are made to be mutually eleasably lockable. it will be understood that alternate means or supporting the sleeves can be provided such as, for examile overhead monorail suspension.

Describing now the operation of employing the transfer leeve in association with the track assembly 34 to extend he waste receiving and storage capacity coming from the :ompactor 30, a plurality of transfer sleeves 10 are placed in a testing tandem position on angle bars 58 between the opposng tubular members 36. When placing the sleeves on the racks, it is important that the handles 20 be located for regisration with the cross members 38. The sleeves are placed in in end to end tandem relationship on the tracks in an approxinate nestable relation. However, it is not necessary that they re initially nestably aligned, since the initial movement of waste through the sleeves will result in the movement of the sleeves down the tracks so that they will arrange themselves in I nesting relation. A bag 26 is placed over the last can on the .rack assembly in an enveloping relationship. The bag is 'endered easier to apply to the sleeve by virtue of the rotatable wheels 42 mounted to the track tubular members, as earlier nentioned. Less preferably, the wheels may be eliminated and my other means used merely to hold the sleeve in a spaced elationship with the track members. The terminal track sec- Lion 50 is telescoped into the preceding track section at the intial starting point of the waste compacting operation.

Thus, with one or more transfer sleeves in an end to end Fashion, as just described, the waste compactor is actuated and waste is commenced to be fed into the first sleeve immediately |n receiving position with the discharge end 32 of the compactor. The sleeves may initially be disposed in nesting relation, however, as mentioned, the effect of the movement of the waste through the first sleeve causes it, if necessary, to move and abut and nest with the next succeeding sleeve and so forth down the line. Moreover, this movement of the sleeve down the track assembly causes the projections 24 of handle 20 to hit angle bar 58 and resultingly rotate it in a counter position, so that the closed portion of the handle 22 is hooked and locked therebyv Therefore, it can be seen that the passing of the waste through the roughly aligned sleeves causes a nesting relation to be established between each nestable sleeve, as well as the locking of the sleeve to the tracks via the handles 20 and rotatable angle bar 58. At this point, it is to be understood that the very first sleeve, that is the sleeve immediately adjacent to the discharge end of the compactor, is not necessarily subjected to this locking action. Meanwhile, as

the waste proceeds through to the last sleeve, the bag is moved off the last sleeve by the waste, ultimately abutting against back plate of the tenninal track section, and the latter section is caused to be drawn outwardly from its telescoped position with the preceding track section of the assembly 34. When it is fully extended, the limiting switch 54 is automatically actuated, shutting off the compactor.

When all the sleeves are filled so that the maximum extension of the terminal track section has activated the limiting switch to cut oh" the compactor, an attendant removes the filled bag and places an empty bag over the last sleeve, upends the sleeve and its bag, raises the sleeve out of the bag by pulling up on the handles 20 and the waste remains behind in the bag. This step is then carried out for each succeeding sleeve until all the bags are filled with waste. Then the sleeves are placed back on the track assembly and the whole operation is ready to be repeated. It is a feature of the invention when the transfer sleeves are removed with the refuse contained therein, the refuse is more readily broken off and the attendant is safe from being cut or injured by any sharp objects contained in the bag. Moreover, the bag is prevented from being cut or torn. It is to be understood that the track assembly and the component parts thereof respectively are made of a suitable rigid material, and that the transfer sleeve is made of any suitable confining material. It is also to be understood that the terms waste and refuse have been used interchangeably throughout the specification, and the meaning thereofwould include also garbage and rubbish.
